ELECTRICAL PRECAUTIONS - Before servicing a pump, always shut off the main power breaker and then unplug the pump - making sure you are wearing
insulated protective sole shoes and not standing in water. Under flooded conditions, contact your local electric company or a qualified licensed electrician for disconnecting
electrical service prior to pump removal.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions. Allow 2½ hours after disconnecting before attempting service.

A. Pump will not start or run.
B. Motor overheats and trips overload or blows.
C. Pump starts and stops too often.
D. Pump will not shut off.
E. Pump operates but delivers little or no water.
F. Drop in head and/or capacity after a period of use.
If the above checklist does not uncover the problem, consult the factory. Do not attempt to service or otherwise disassemble pump. Service must be
performed by Zoeller Authorized Service Stations. Go to www.zoellerpumps.com/servicestations to find the Authorized Service Station in your area.
